Purpose: This study aimed to compare the efficacy of and patient satisfaction with the wide-awake local anesthesia with no tourniquet (WALANT) technique in open cubital and carpal tunnel release surgery.Methods: From January 2016 to February 2017, 20 cubital tunnel syndrome (CuTS) patients were in a wide-awake (WA) group and 22 in a general (GA) anesthesia group in . Also, 20 carpal tunnel syndrome (CTS) patients were in a WA group, 22 in a local anesthesia (LA) group, and 20 in a GA group. Injection pain, perioperative pain, and postoperative pain were assessed using a 10-point pain VAS. In CuTS, functional outcome on the “quick” Disabilities of the Arm, Shoulder, and Hand questionnaire were evaluated. In CTS, subjective outcomes were assessed using the Korean version of the Michigan Hand Outcomes Questionnaire.Results: Both CuTS and CTS showed significant postoperative pain reduction in group WA. In CuTS, group WA had less pain than group GA up to 48 hours after surgery (P<0.05). Supplemental opioid injections were used on hospitalization day by 12% of group WA and 35% of group GA. In CTS, the postoperative VAS scores in group WA were lower during the first 24 hours than groups LA and GA (P<0.05). Opioid injections were used on hospitalization day by 5% of WA, 18% of LA, and 32% of group GA. There was no difference in postoperative functional outcomes according to anesthesia method in CuTS or CTS.Conclusion: Cubital and carpal tunnel surgery using the WALANT technique was comparable in function to other anesthesia methods and superior for pain. Immediate postoperative pain was much lower than other groups, which could reduce the use of opioids during hospitalization.
